2. Package Contents
Verify that your package contains the following items:
- Plantronics SupraPlus HW251 Monaural Headset
3. Setup
Follow these steps to connect and prepare your headset for use:
- Connect the Headset: Plug the headset's Quick Disconnect (QD) cable into a compatible Plantronics Polaris Cable (model 2719001, sold separately) or directly into your corded telephone's headset jack. Ensure the connection is secure.
- Position the Headset: Place the headset over your head with the ear cushion resting comfortably on one ear. The headband should sit gently on your head.
- Adjust the Microphone: Gently bend the microphone boom so that the microphone is approximately two finger-widths from the corner of your mouth. Ensure it is positioned for optimal voice pickup without obstructing your vision.
4. Operating Instructions
Once connected, operate your headset as follows:
- Making/Receiving Calls: Use your telephone's standard call controls (e.g., headset button, dial pad) to initiate or answer calls. Audio will be routed through the headset.
- Volume Control: Adjust the listening volume using your telephone's volume controls. The headset itself does not feature integrated volume controls.
- Mute Function: If your telephone or Polaris cable has a mute function, activate it to temporarily silence your microphone.
5. Maintenance
Proper care ensures the longevity and performance of your headset:
- Cleaning: Use a soft, dry cloth to wipe the headset. For the ear cushion, a slightly damp cloth with mild soap can be used, ensuring no moisture enters the speaker or microphone. Allow to air dry completely before use.
- Storage: Store the headset in a clean, dry place away from extreme temperatures and direct sunlight. Avoid wrapping the cable tightly around the headset.
- Cable Care: Do not pull on the cable to disconnect the headset. Always grasp the plug or Quick Disconnect connector.
6. Troubleshooting
If you encounter issues, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound in headset | Headset not properly connected; telephone volume too low; incorrect telephone setting. | Ensure all cables are securely connected. Increase telephone volume. Verify telephone is set to headset mode. |
| Microphone not working | Microphone muted; microphone boom incorrectly positioned; faulty connection. | Check if the mute function is active on your telephone or cable. Reposition the microphone boom. Reconnect the headset. |
| Echo during calls | Telephone volume too high; telephone compatibility issue. | Reduce the listening volume on your telephone. Consult your telephone's manual for headset compatibility or adjustments. |
